Greenhouse Workers Teach Researchers How To Grow Plants

Growers know that nutrient-rich potting mixes and adequate lighting are important when growing healthy plants. At the Cornell University Agricultural Experiment Station (CUAES), scientists and greenhouse workers are teaching researchers these basic principles. According to an article provided by Cornell University, Andy Leed, greenhouse manager at Cornell University, demonstrated the difference potting mix can make at a March open house for researchers across campus. Leed showcased flats of arabidopsis, a choice plant for researchers concerned with genetics and molecular biology.  Four flats boasted a vigorous carpet of healthy plants, but another three flats looked sickly. “I saw a lot of raised eyebrows,” Leed says in the article. While many researchers might assume the differences came from pest exposure or germination issues, potting soil was to blame. According to Leeds, researchers “need to know if the potting medium they use is compatible with their crop and irrigation protocol.” According to the […]

Orchid Grower: Sphagnum, Bark Both Have Place As Medium

Dear Greenhouse Grower, As a fellow commercial orchid grower, I enjoyed the video on your website comparing bark and sphagnum moss as phalaenopsis orchid substrates. While I found Rocket Farms’ and Marc Clark’s take to be very interesting, I would like to add our perspective. Westerlay Orchids grows more than 1 million plants annually in specially formulated orchid bark and a couple hundred thousand in sphagnum moss. We believe great plants can be produced in both. Great plants have vigor and remain vibrant in customers’ homes. We believe the key to this performance is active roots. We find that our larger phalaenopsis (5-inch) grow better in our greenhouse and perform better in the home when they are in bark because they grow more and better roots. We find plants in larger moss pots do not build up the same active root mass. For our smaller plants (3-inch), moss works well […]

Growing Media Supplier Loses $39 Million Lawsuit Over Fertilizer

Two Canadian farmers won a multimillion dollar lawsuit last week against British Columbia-based Sun Gro Horticulture and Woodburn Fertilizer Company, claiming Sun Gro’s Multicote 15-9-12+ Minors controlled-release fertilizer cost them millions of dollars in lost crops and customers. Sun Gro is the designer of Multicote and Woodburn Fertilizer is the company that manufactured it. According to OregonLive.com, Jag Aujila, who owns JRT Nurseries in British Columbia and Washington state, was awarded nearly $12 million in direct economic losses for the death of his plants, $22.5 million for the loss of customers and nearly $5 million in interest. Aujila’s attorney convinced a jury Multicote killed 4.1 million of JRT’s blueberry plants and hundreds of thousands of other plants based on side-by-side comparisons between crops with Multicote and crops without it. “It was kind of like a giant sixth-grade science experiment: Wherever the other fertilizers were used, the plants thrived,” says Larry […]

Fafard’s Advice For Managing Through The Peat Shortage

The North American horticultural industry is currently dealing with a peat moss shortage caused by poor weather conditions in eastern Canada. The wet conditions impacted all peat companies with bogs in Quebec, New Brunswick and Nova Scotia, where two-thirds of the peat is harvested. Eastern Canada produced only 30-40% of its anticipated harvest for 2011. The variables regarding how this will affect our industry and individual growers are the following: 1) How much carry-over inventory from the 2010 harvest did each company have on-hand this summer? 2) How much peat from western Canada can economically be shipped eastward to cover shortages? 3) How much peat and mix do growers have on-hand due to a poor 2011 sales year? 4) How much peat can be economically shipped from European sources to cover shortages in the eastern US? 5) How much has our industry been impacted over the past few years due […]

Peat Shortage Among Topics Discussed At Field Day

Syngenta’s Discovery Center, Anderson, S.C. Syngenta Flowers recently hosted 60-plus growers and brokers at a fall field day last month in Anderson, S.C. The field day was an opportunity for Syngenta Flowers and Fafard to answer questions with growers on this year’s peat shortage. Syngenta indicates growers are considering growing media with less peat and more bark, coir and other ingredients. “We’re able to show them how we make these mixes and how our genetics respond to them,” says Jamie Gibson, technical services manager with Syngenta.

Fafard Gains Veriflora Certification For Its Peat Production

Fafard has received the Veriflora certification for responsible horticultural peat moss and peatlands management, it reports. The certification allows Fafard to market its peat products as certified. Most of Fafard’s blends include peat moss. The Veriflora program is an extensive one that focuses on the expected environmental practices and also social and product-quality standards. "Receiving the Veriflora certification … elevates us in the industry and demonstrates our concern for day-to-day operations, our producers," says Bruce Adams, Fafard head of operations. Veriflora is run by Scientific Certification Systems, a third-party certifier. For Fafard peat moss to receive the certification, Fafard had to prove it restores wetland ecosystems, reduces its environmental footprint during production, conserves energy, reduces residual materials in landfills and ensures fair labor practices and community benefits. It’s a long process to gain certification, says bog operations manager Ernie Basque. Learn more about Fafard at Fafard.com. Learn more about VeriFlora […]

The Peat Shortage: A Look At The Next Harvest

Paul Short Paul Short, the president of the Canadian Sphagnum Peat Moss Association (CSPMA), weighs in on the peat industry’s 2012 harvesting plans, the availability of retail peat next spring and other peat-related issues surrounding this year’s peat shortage. GG: CSPMA members represent nearly all of North America’s peat production: How are your members advising growers to react in terms of buying and using peat moss PS: The [peat] industry is encouraging each grower to work directly with the peat producer to identify solutions on a case by case and company by company basis. GG: What effect is this shortage having on pricing and the availability of straight peat versus mixes? PS: To date, what is emerging from producers is a deliberate trend to prioritize mix volumes over straight peat supply. The outcome may be a challenge to the availability of straight peat products. GG: If growers cannot access the […]

Q&A: Charles Bethke Answers Your Questions

Charles Bethke weighs in on questions that went unanswered during the hour-long “Managing Through The Peat Shortage” webinar Oct. 18. Q: What does the p in pH stand for? A: That’s the negative log of the hydrogen ion activity. It’s a chemical designation for the concentration of hydrogen ions floating around loosely in a solution. Q:  Please clarify what "incubate the mix" means for folks. Often times they do not wet the mix in this process. A: When I used incubate I mean moisture the soil to normal use levels and store at use temperatures for two or more weeks. That will give us the impact of the various components in the blend. Q: Do you expect companies that offer pre made mixes in filled flats, pots or bulk bags to still offer these as in the past or will these higher priced peat based products be short as well? […]

Jiffy’s Advice For Managing Through The Peat Shortage

With the weather-induced peat shortage having a tremendous impact for the 2012 growing season, most growers are paying more attention to peat and other growing substrates than ever before. At Jiffy, we have many decades of producing peat products, from Jiffy Pellets to peat pots to Preforma. Now, we have blended substrates with Jiffy Mix powered by TREF. Some background might be helpful as growers continue to evaluate their different growing options. As growers know, all peat moss is not the same. Even peat from the same bog may have different characteristics based on harvest method and handling, as well as fraction size. Typically, longer fibers, along with other mix components, will minimize soil compaction. When blended in the correct percentages, those fiber lengths will provide a unique and balanced mix based on crop timing and container size. When we look globally at each market, the European growers tend to […]

Rekyva’s Peat & Its Effects On Flowers & Veggies

Most of the environment factors that influence the growth of plants and their productivity can be controlled (roots’ medium, fertilization, light, temperature, humidity, etc.). Substrate is one of the factors that truly influence the growth of plants and their development, productivity, since it determines the quality of the roots system. When preparing soil or substrate for growing, it is important to consider their needs and the use. Most often for flowers, easily aerating and water permeable mix of different soils with different reactions is prepared. Substrates for roots of plants must provide as good as possible aeration conditions for the uptake of nutrient. Peat mixes, in which one of the compounds is zeolite, are widely used. The use of bentonite in the production of substrates is also being investigated. In April to June of 2011 in the Botanical Garden of the Faculty of Natural Sciences of Šiauliai University, an investigation […]
